Macro IconsFollow

Is there any way to import new macro icons into the game? Using current ability icons can get confusing and the default icon sends my OCD into overdrive.

A similar question, is it possible to set the tooltips on a macro to show up for a main spell? I use swiftcast before fire II and fire III when I am fate grinding so I can just jump off my mount and get a fast hit off, but haven't found a way to get them to show the tooltips also. Not that its very important, just a personal preference,
